Image compositing apparatus and methodology for the creation, in a defined volume of three-dimensional space, of a composite organization of plural images/visual phenomena, including at least one projected real image (104), displayed in formats including (a) front-to-rear, (b) side-by-side and (c) overlapping and intersecting, adjacency. The apparatus incorporates different unique arrangements of visual sources (110, 112), and optical elements including concave refloc- tors (114), beam splitters (116) and image-forming/image transmissive scrim screen structures (334). In one important modification of the system, which does not necessarily re- quire compositing, a projected real image is derived from an image-producing data stream containing three-dimensional image cues selected from the group consisting of shading occlusion, perspective, motion parallax, size vs. depth, light (chroma value) vs. depth and definition vs. depth. In a fur- ther important modification of the invention, a system (620) is proposed which allows a viewer/user to interact directly with a projected real image, in a manner allowing the ma- nipulation of one or more characteristics or aspects of the image.

Appareil de composition d'images, et procédé de création, à l'intérieur d'un volume tridimensionnel donné, d'une organisation composite de phénomènes multiples de représentation/visualisation comprenant au moins une image réelle projetée (104) présentée en formats comprenant un agencement (a) recto/verso, (b) côte-à-côte, (c) à chevauchement et intersection. L'appareil comporte différents arrangements particuliers de sources visuelles (110, 112) et des éléments optiques y compris des réflecteurs concaves (114), des diviseurs de faisceaux (116), et un écran mousseline (334) de formation et transmission d'images. Dans l'une des variantes importantes du système qui ne demande pas nécessairement de composition, l'image réelle projetée dérive d'un flot de données génératrices d'images contenant des instructions d'exécution des images tridimensionnelles tels qu'ombrage, occlusion, perspective, parallaxe de mouvement, et rapports taille/profondeur, densité lumineuse/profondeur et définition/profondeur. Dans une autre variante importante figure un système (620) permettant à l'utilisateur du système d'interagir directement sur l'image projetée de façon à pouvoir influer sur une ou plusieurs caractéristiques ou aspects de l'image.
